A deeply savoury, slow-cooked lamb stew flavoured with aromatic whole spices and thickened with roasted chickpea flour. The meat turns fork-tender in a velvety, warmly spiced gravy.
Warm 114 g mustard oil in a wide, heavy-bottomed pan over medium heat. Add roughly half of the 250 g sliced onion and fry for 5 to 7 minutes until crisp and browned, then transfer with a slotted spoon to drain on paper towels.
Return the pan to medium heat. Tip in the whole spices and cook for 30 seconds, until the cardamom skins darken in colour.
Add the rest of the sliced onion, the ground spices and pastes, 152 g whisked plain yogurt, and salt to taste. Sauté for around 2 minutes until the oil glistens and separates from the sauce.
Crumble the crispy fried onions by hand into the pan and stir for 1 minute. Add 500 g lamb pieces and 1500 g stock, then heat until just below boiling. Drop the heat to low, cover, and simmer gently for 1 to 1½ hours until the meat is thoroughly tender.
In a small bowl, mix 4 tablespoons roasted chickpea flour with 4 tablespoons water to form a smooth paste, then pour it into the curry. Stir in the finishing spice, replace the lid, and simmer for another 5 minutes. Remove the lid and balance the seasoning with extra salt if needed.
Use 80% of the weight, finely shredded and browned slowly with a pinch of asafoetida. Replicates the bulk and natural sweetness in gravies without allium.
Use 1 g ground for 4 g whole (or 1 small pinch per 2 to 3 whole cloves). Add with spice powders; disperses intense warmth quickly, so use with restraint.
Allspice berries
Use 100% of the weight whole in tempering. Imparts a warm, clove-like aromatic profile combined with hints of nutmeg and cinnamon.
Use about a third of the weight (0.5 g ground for a 2.5 cm piece), stirred in with the ground spices rather than fried whole, since the powder burns quickly.
Use 50% of the weight and stir in near the end of cooking. Adds warmth and depth since it contains ground coriander, but introduces stronger spices like clove and cinnamon.
Steep a tiny pinch (0.1 g per 2 g turmeric) in 2 tbsp warm water; use to match the rich golden hue. Contributes an aristocratic, honeyed floral flavour rather than earthy bitterness.
For crisping batters or binding cutlets: use 50% to 60% of the weight. Produces a very crisp shell but lacks the earthy, roasted nutty flavour of besan.
